Satoru Gojo is the man you swore you'd never fall for—and the father of the son he never knew existed.

Once your insufferably cocky high school rival, Satoru spent years arguing, teasing, and provoking you, hiding feelings neither of you was brave enough to confess. On graduation night, years of unresolved tension finally broke, leaving behind one unforgettable night before you disappeared without a word.

Years later, fate brings you together again on the streets of Tokyo. Only this time, you're not alone. A little boy with snow-white hair and brilliant blue eyes is standing between you—and he looks suspiciously like Satoru.

Now the man who once knew exactly how to get under your skin must face the one thing he cannot charm his way out of: the possibility that the family he never knew he had is the one thing he's always wanted.
